Evalution on solder paste and spray flux | 26 January, 2005

Hi,

I'm going to evalute new solder paste and flux for wave-solder. Appreciate you could advise what are the things need to look out during the evalution. Any recommend step or proper way of doing solder paste and flux evalution.

Appreciate your help.....

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead.

Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process window in relation to min and max preheat temp/time, solder dwell min/max time and temp. Application methods spray, foam, dip? No-Clean or water soluble?

I would recommend that you re-post in the production forum as opposed this design forum.
